This Fall Staple Has Been Around For So Long, You Probably Forgot How to Wear It

We're sure that, at one point, you owned a sweater dress you wore to death, perhaps styled with knee-high boots or tights. Blake Lively's Gossip Girl character Serena van der Woodsen provided more than enough inspiration a few years back, after all. But the one-and-done outfit happens to look a little different these days, with midi length versions being introduced in electrifying shades, and ladies on the street coming up with impeccable style rules — i.e. "must layer with shirting underneath." The sweater dress is being reintroduced into our wardrobes as a trend this season, which means there are cozy, oversize silhouettes abound for you to shop. That is, right after you take our advice for how to wear them.
